ERA Cadre Civil Servant Exam cheat sheet

Ethiopia's federal structure: 12 regional states plus 2 chartered city administrations (Addis Ababa, Dire Dawa); the House of Federation interprets the Constitution.

Executive power sits with the Prime Minister as Head of Government; the President is a ceremonial Head of State elected by the joint session of the two Houses.

The House of Peoples' Representatives has 547 seats; members serve 5-year terms; the chamber nominates the Prime Minister and approves the Council of Ministers.

Key national policy frames to know: Ten-Year Development Plan (2021-2030), Homegrown Economic Reform, and the Green Legacy Initiative.

Grand Ethiopian Renaissance Dam (GERD) is on the Blue Nile in Benishangul-Gumuz; the Abbay/Blue Nile supplies roughly 85% of Nile flow at Aswan.

African Union headquarters is in Addis Ababa; AU Agenda 2063 is its 50-year continental development framework.

Sustainable Development Goals: 17 goals, 169 targets, adopted 2015 with a 2030 horizon; SDG 9 covers infrastructure and roads.

Currency: Ethiopian birr (ETB), issued by the National Bank of Ethiopia; fiscal year runs 8 July to 7 July (Hamle 1 to Sene 30 in the Ethiopian calendar).

Subject-verb agreement: singular subjects take singular verbs; intervening phrases do not change the number ('The list of items is long').

Tense sequence in reported speech: present becomes past, past becomes past perfect, will becomes would.

Conditionals: zero (general truth), first (real future), second (unreal present, 'were' for all persons), third (unreal past, had + past participle).

Active to passive: object becomes subject, verb becomes be + past participle, agent introduced by 'by'.

Common confusions: affect (verb) vs effect (noun); principal (main) vs principle (rule); lie (recline) vs lay (place something).

Parallel structure: items in a list or comparison must share grammatical form ('reading, writing, and speaking', not 'reading, writing, to speak').

Prepositions of time: in (months, years), on (days, dates), at (clock times); 'since' takes a point in time, 'for' a duration.

Formal register for official writing: avoid contractions, slang, and first-person opinion; prefer passive or impersonal constructions in reports.

Keyboard shortcuts: Ctrl+C copy, Ctrl+X cut, Ctrl+V paste, Ctrl+Z undo, Ctrl+Y redo, Ctrl+S save, Ctrl+P print, Ctrl+F find.

Absolute vs relative references: $A$1 locks row and column; A1 shifts when copied; F4 toggles the dollar signs.

Common spreadsheet functions: SUM, AVERAGE, COUNT (numbers only), COUNTA (non-empty), IF, VLOOKUP, SUMIF, ROUND.

File extensions map to applications: .docx Word, .xlsx Excel, .pptx PowerPoint, .pdf portable document, .csv comma-separated values.

Email: BCC hides recipients from each other; CC is visible to all; Reply-all includes every original recipient.

Storage units: 1 byte = 8 bits; 1 KB = 1024 bytes; 1 MB = 1024 KB; 1 GB = 1024 MB; 1 TB = 1024 GB.

Security basics: strong passwords mix length and character types; phishing is unsolicited mail seeking credentials; never share passwords.

Backup rule 3-2-1: three copies, two media types, one copy off-site.

Core civil service values: impartiality, integrity, accountability, transparency, responsiveness, and service to the public interest.

Conflict of interest rule: a public officer must declare any private interest and recuse from decisions affecting it.

Confidentiality duty: official information is used only for official purposes and not disclosed after leaving service without authorization.

Gift and benefit rule: officers may not accept gifts or favours that could influence official judgement; nominal courtesy gifts are declared.

Good governance characteristics: participation, rule of law, transparency, responsiveness, consensus orientation, equity, effectiveness, efficiency, accountability.

Whistleblower protection: reporting suspected corruption in good faith is a duty; retaliation against a good-faith reporter is misconduct.

Administrative fairness: hear the affected person before an adverse decision (audi alteram partem) and give reasons for decisions.

Political neutrality: civil servants serve the government of the day loyally but do not campaign for parties or use office for partisan ends.

Fayol's functions of management: planning, organizing, commanding, coordinating, controlling; his 14 principles include unity of command and scalar chain.

POSDCORB (Gulick and Urwick): Planning, Organizing, Staffing, Directing, COordinating, Reporting, Budgeting.

Weber's ideal bureaucracy: hierarchy, written rules, division of labour, impersonal selection by merit, career structure.

Span of control: the number of subordinates one manager supervises; wider spans flatten hierarchy and require more delegation.

Delegation requires authority, responsibility, and accountability together; accountability cannot be delegated away.

Line functions give direct command over core work; staff functions advise and support without command authority.

MBO (Drucker): objectives set jointly, cascaded from top to bottom, with periodic review and appraisal against agreed targets.

Budgeting cycle: formulation, approval by legislature, execution, monitoring, and audit; programme budgeting links funds to outputs.

Road hierarchy: trunk/primary, secondary, tertiary, and rural/access roads; design speed and width decrease down the hierarchy.

Design speed drives geometry: horizontal curve radius R relates to speed V and superelevation e via R = V² / (127(e + f)), with f the side-friction factor.

Stopping sight distance SSD = 0.278 V t + V² / (254(f ± g)), where t is reaction time in seconds and g the grade.

Vertical curves: crest curve length depends on stopping sight distance and algebraic grade difference A; sag curves also consider headlight sight distance.

Pavement layers: subgrade, sub-base, base, and surface (asphalt or concrete); each layer spreads load to reduce stress on the layer below.

CBR (California Bearing Ratio) expresses subgrade strength as a percentage of a standard crushed stone; it guides pavement thickness design.

Design traffic uses Equivalent Standard Axles (ESA) accumulated over the design life; a standard axle is 8.2 tonnes (80 kN).

Drainage: side drains, culverts, and cross-fall (typically 2-3%) remove water quickly; water is the leading cause of pavement failure.

Asphalt compaction must occur within the rolling temperature window; too cold means inadequate density and early rutting.

Compaction is measured as a percentage of maximum dry density from a Proctor test; field density is checked by sand replacement or nuclear gauge.

Pavement distress types: rutting, fatigue (alligator) cracking, potholes, raveling, bleeding, and reflection cracks; each has a distinct cause.

Routine maintenance covers pothole patching, crack sealing, and drain clearing; periodic maintenance covers resealing, overlay, and reconstruction.

Asset management cycle: inventory, condition survey, performance modelling, priority ranking, works programming, and budget allocation.

Condition indices (e.g. PCI, IRI for roughness) allow objective prioritization; IRI is measured in metres per kilometre of vertical displacement.

Life-cycle cost analysis compares options on initial cost plus discounted future maintenance, rehabilitation, and user costs.

Road fund principle: dedicated, ring-fenced revenue (fuel levy, transit fees) for road maintenance rather than general budget competition.

Procurement methods: open competitive bidding (default), restricted bidding, request for quotations (small values), direct purchase, and single-source for justified exceptions.

Bid evaluation follows published criteria only: responsiveness check, then technical and financial evaluation; no criterion may be introduced after bid opening.

Bid security (tender bond) protects against withdrawal; performance security (often 10% of contract price) protects against default after award.

Contract types: lump-sum (fixed scope), unit-price/measured (quantities re-measured), cost-plus, and design-build; risk allocation differs in each.

Variation orders change scope, quantity, or timing; they require written instruction and value limits defined in the contract.

Payment certificates are issued after measurement and certification; retention is typically withheld (often 5-10%) until the defects liability period ends.

Financial controls: segregation of duties, commitment accounting, budget versus actual variance analysis, and internal plus external audit.

Public procurement principles: transparency, competition, economy, efficiency, fairness, and accountability; records must be retained for audit.

Hierarchy of controls, most to least effective: elimination, substitution, engineering controls, administrative controls, personal protective equipment (PPE).

PPE is the last line of defence because it protects only the wearer and only if worn correctly; it never replaces engineering controls.

Site hazards: excavation collapse (shoring and benching required beyond safe depth), falls from height, plant-pedestrian interaction, and electrical contact.

Traffic management at road works: advance warning signs, taper, buffer zone, work zone, and termination area, with trained flag persons.

Hazard identification uses a risk matrix scoring likelihood against severity; residual risk is re-assessed after controls.

Environmental impact assessment (EIA) precedes major works; mitigation covers dust suppression, silt traps, noise limits, and spoil disposal.

Occupational health: silica dust from cutting concrete causes silicosis; hearing loss from plant noise is prevented by monitoring and protection.

Incident reporting: record near-misses as well as injuries; investigate root causes, not just immediate causes, and track corrective actions to closure.
